REGISTERING DEVICE Application led June 21, 1929. Serial No. 372,738.

This invention relates to a registering device for the4 production ofchangeable lpictures :of the ty e set forth in my prior atents No.1,150,3 4, of August 17, 1915 and No.

5 1,260,682, of March 26, 1918. Such changeable pictures arestereoscopic and may be either opaque or transparent, although theinvention is described primarily in Connection with opaque stereoscopicpictures.

An opaque changeable or stereoscopic picture would consist of a sheet ofcelluloid (or other transparent material) having its front surfaceribbed to form cylindrical lenses and having ajpositive opaque pictureof the stereoscopic type on or adjacent to its rear surface.

A diiiiculty in the production of such changeable pictures of large sizeis that of obtaining precise registry between the ribbed lcelluloid andthe positive picture. For instance, the positive may be printed onordinary photographic paper and then cemented to the celluloid. But thepaper is likely to change its dimensions in the ordinary photographicprocess of developing, fixing,

Washing and drying, and even if means are employed to restore it to thecorrect dimensions, itis likelyto be difficult or troublesome to cementit to the Celluloid in precise regis- .To overcome these diiculties Ipropose to coat `the back of the celluloid sheet with a sensitivephotographic film, and to rint the positive picture directly upon thislm from 35 a negative registered properly with the cylindrical lenses onthe Celluloid.

y In order to print from a negative onto a film on the back of thecelluloid as I propose, it is very desirable to have some device for 4oinsuring precise registry of the negative with the cylindrical lenses ofthe celluloid, without the use of light' in such a Way as to injure thefilm. This is provided inv my invention.

Iny the accompanying drawings:

in different positions;

Fig. 4 is a plan View of the device for holding the lined screen;

Fig. 5 is a vertical transverse section of the same device;

Fig. 6 shows an enlarged cross section of the ribbed celluloid inposition on its support; and

Fig. 7 shows a cross section of the ribbed Celluloid on a different kindof support.

At 11 is a similar movable spring pivoted as at l2 and is used to holdthe support 6 with the ribbed celluloid 7 in the horizontal position. At13 is a catch attached to the. Tear wall of the box by which thecelluloid support 6 may be held in the position shown in ig. 2 While thecelluloid sheet is being put into place.

- In order to hold the Celluloid 7 in place on the grooved support 6before ithas been raised to the horizontal position it may be desirableto use a vacuum or suction device, as illustrated. Whether this isdesirable will depend on hovvr much tendency the celluloid has to curl.The support 6 has inner channels as at 14 with several openings 15extending therefrom to the grooved surface. These channels 14 areconnected by a flexible hose 16 through a valve to a vacuum or suctionpump (not shown). After the celluloid has been laced on its support, itmay be held in positlon by the application of vacuum or suclon.

If the vacuum or suction is to beused, it is desirable that the groovesin the support 6 should fit closely the ridges in the celluloid, asshown in Fig. 6. If the vacuum or suction is not to be used, the ridgesmay be of some other shapeiperllzaps more conveniently machined, as ing.

It is desirable that the lined screen 2 should be held in its support 3in such a way that its position can be accurately ad usted. How this canbe done is shown in igs. 4

turnin the screws 19; and the yclamps 17 can be `eld in position by thescrews 20, which pass through slotted holes 21 in the clamps 17 lnto thesupport 3. The central portion of the su port 3 is left o en so thatlight .can pass t rough it. In ig. 4 the white lines are drawn heavierin the central portion where they ma be illuminated from below.

. Located in t e bottom of the box l5 is an electric lamp 22, or othersource of illumination, while in the upper portion 23 of the box orcasing 5 is another lamp 24 for illuminating and exposing the oppositesides of the negative and screen.

. The position of the lined screen 2 on its Asupport 3 is so adjustedthat when the screen and its su port are raised to the' horizontalosition s own in Fig. 1, each transparent ine of the screen occupies thesame position as the ltop of one of the ridges in the support 6 occupieswhen itis raised to the horizontal position, as in Fig. 3. This adjustment'may be made by placing two compound microscopes with cross-hairsin their eyepieces in a vertical position above the celluloid support 6,when raised to a horizontal position,

and are focused with the cross-hairs over the same ridge in the support.Then by lowering the support 6 and raising the lined screen 2, themicroscopes'may be focused on thelatter by adjusting the screen so thatone of the lines ofthe screen is exactly under the cross-hairs of themicroscopes. This vadjustment may be done once for all when theapparatus is set up.

The negative 1 is placed inthe position g shown `and the lined screen 2is placed in contact below it asin Fig. 1. The negative and screen areviewed from above by light transmitted from the lamp 22 and the negativeis so registered with the lined screen that the division lines betweenthe picture strips in the negative are opposite the transparent lines inthe lined screen. It can readily be determined when this registration isobtained by the appearance of the negative as seen by the light passingthroughthe screen. The negative is fixed in position by means of theclam s 25. i

Wlth the lamps 22 and 24 turned off and with no other source of lightexcept perhaps light of any kind that will not materially affect thephotographic surface, the ribbed celluloid 7 withitsphotographic-sensitive film 26 which coats the back thereof turneduppern'iost is placed on the support 6 with the ribs of the celluloidVfitting into the grooves in the support, the support meanwhile being insome convenient position as in Fig. 2. The support 6 -with the celluloid7 is then raised until the photographic surface is in contact wit-h thenegative as in Fig. 3, the lined screen 2 .having been lowered away fromthe negative. The ribs of the celluloid 7 are then in proper registrywith the picture strips of the negative 1. l

The lam 24 is then turned on a suflicent length of tlme to properlyexpose the photo- Jgr'iphic surface 26 Iunder the negative 1.

he celluloid is then removed from the a paratus and its photographicsurface is e-l stead of the lined screen and the celluloid support beingh ung on hinges below the plane of the negative, they might be placedupon a support moving horizontally on a trac under the negative withmeans of raising each successlvely upward under the negative, or

means of moving the negative downward onto each successively.

This device is intended primarily for use inY producing stereoscopicpictures. ever, it may also be used for chargeable pictures that are notstereoscopic. l t may also be used in 4making transparent/stereoscopicpictures, and is not to be limited to those which are opaque.

Howp The linedscreen 2 may be replaced by a i sheet of ribbedtransparent material with.

the ribbed surface downward, if desired. This material should be soshaped that light reaching itfrom the lamp 22 below is focused onthesurface of the negative 1. vIf this ribbed material requiresadditional stiffness, it may be supported on a sheet of clear lass.

In the making of opaque stereoscopic pictures on celluloid, having aphotographic .l

coating on the back, after the hotographic image has been developed andxed, the 1c ture should be backed with some opaque wiiite or lightcoloredmaterial such as paper or paint. This reflectsv the light thatfalls from the front onto the clear spaces of the photographic image,and renders the image more clearly visible.

In the drawings, the size of the ridges on the celluloid and its supportis exaggerated for the sake Vof clearness.

The general principles of the registering device are presented by Figs.1, 2 and 3. The ne ative is designated by the numeral 1. This negativemay be made in accordance with my former Patent No. 1,260,682, March 26,1918, and comprises the exposure of a sensitized surface throughaJ linedscreen to an object while relatively moving the sensitized surface andlined screen. At 2 is shown a lined screen consisting of` a sheet ofglass or other suitable material carrying alternate o aque andtransparent lines, as shown in ig. 4, the number per inch being the sameas in the lined screen used in the camera in which the negative wasproduced. The screen 2 is carried ona support 3, hinged tive coatin '10.When the spring is turned forward as in Fig. 1 it is used to hold thelined screen support 3 in its horizontal position. When the spring isnot required itfmay be turned back against the back wall of the box, asin Fig. 2. When the lined screen is not in useV it may be allowed tohang down as in Figs. 2 and 3.
